ROLLER MOUNTING.

Applicatioil filed lYunes 13,1922. Serial No. 568,057.

To all whom it myconaem: c

Be it known that I, EMIL SOHNEEBELI, a citizen of Switzerland, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements inRoller Mountings, of which the following is a detailed specifcation. a

This invention has to do generally with a mounting for rollers such, for instance, as

are used in paper and textile mills, printing presses, etc. Rollers of the character above referred to are comparatively long and heavy and are usually mounted by means of trunnions extending from their ends and carried 1n stationary bearings. These mountings are rather inefficient and frequently give trouble, as it is more or less difficult to properly align the bearings and to maintain them in proper alignment.

lt is an object of this invention to provide a roller mounting which is simple and effective and which allows the roller to be easily positioned and maintained in a machine.

Thel various objects and. features of the invention will be best and more fully understood` from the following detailed description of a typical preferred embodiment of the invention, throughout which reference is had to the accompanying drawlngs, 1n

Fig. 1 is a view showing a roller mounted in accordance with the present invention; Fig. 2 is an enlarged detailed sectional view showing in detail the mounting provided by the present invention; and ig. 3 is a transverse sectional view taken as indicated by line 3-3 on Fig. 2.

In the drawings numeral 10 designates, generally, a stationary arbor, the ends of which are supported by brackets 11 secured 4 'to asuitable base 12. Theend portions 13 of the arbor 10 are somewhat smaller in diameter than the rest of the arbor forming outwardly facing shoulders 14 near the ends of the arbor. The brackets 11, which l have disclosed in the drawings, are of simple construction, being formed with openings 15 which slidably carry the outer ends of the end portions 13 of the arbor, and being provided with set screws 16 for holding the arbor firmly against movement. riihese screws lmay be omitted if desired without impairing the operation of the structure provided by my invention.

The roller 17 illustrated in the drawings, is a straight smooth roller and is rotatably mounted on the arbor 10 by means of bearings 18. However, the invention may be used in connection with various types of rollers, for instance, the rollers might be ribbed or fluted rather than plain. It is preferred that the roller 17 be in the form of a sheet metal tube or cylinder of the desired size and configuration and that it be provided at its ends with inwardly extending flanges 20. The bearings 18 are located at the ends of the roller 17, and as they are the same in construction and operation, will proceed to describe only one of them in detall, it being understood, of course, that such description is applicable to both of A with theend of the roller 17, and a plurality of supporting members 23, say for instance ball bearings, rotatably supporting the outer ring on the inner ring. The innerring 2'1 of the Ibearing is held between an inner collar 24 which engages the shoulder 14 and an outer collar 25 which clamps the inner ring 21 andinner collar 24 together and against the inner shoulder 14. Although various means may be provided for clamping the outer collar`25 toward the inner ring 2l and inner sleeve 24, it is preferred that there be a plurality of set screws 30 carried by the collar 25 in an inclined position so tha-t they can be operated to engage the arbor 10 at an angle and wedge the collar 25 toward the ring 21 and inner collar 24. This particular means is extremely simple, compact, and effective. The outer ring 22 of the bearing 18 is held in a carrier 29 which is attached to the roller 17.

The carrier 29 has a. flange 31 which extends outwardly from it and is attached to the flange 20 extending inwardly from'the end of the roller. The flange 31 may be attached to the flange 20 by means of a plurality of screws through it and the flange 2O and screw thread into a ring 33 at the inner side of the ange 20. The carrier 29 has a part 35 which extends inwardly to but does not contact with the cylindrical portion 36 of a flange 37 which extends from the inner end of the ,inner collar 24. A ring of packing 38, preferably soft packing, -is arranged.

32 which extend inwardly withi :the parts 35 and 36 to seal the-joint collar 25.

betwe n them, andA a spring ring 39 is ar- 1t outwardly as it wears ranged within the dpacking 38 to hold it in position and tofee away.A y

A flange 40 extends outwardly from the carrier 29 and has (a A recess 41 is provided in the angle 40 at the collar to carry packing 42 w lchopcrates to seal the joint between' the collarA and ange. The packing 42 is held between the collar 25 and iange 40, by a' ange 45 which extends outwardly from the The flange 45 overhangs the greater portion of the flange 40 so that it v catches any oil or other liquid that is thrown ,'from the flan e 40 during operation-of the roller. An o1 groove 50 is provided in the collar 25 and extends from the outer part of the collar tol the bearing 18 in order that oil or grease may be fed to the bearing from a grease cup .51, or the like.v Oil'or greasefed to the bearing through the groove is prevented from escaping from the bearing by lthe packing 38 and 42.

With the construction hereinabove described the roller 17 may be properly mount-V..

ed and adjusted on the arbor 10 prlor to its being installed in the machine so that it can be properly and effectively mounted in the machine by simply supporting the ends ofv the arbor 10 in suitable brackets, or the like.

, With the construction provided by the' present invention there is little or no danger of the bearings getting out of line andtherey is no liability of the roller and roller mounting being injured if the brackets carrying the ends of the arbor do get out of line.

Further, it is lto be noted that the construction is particularly simple "and compact and that it will operate 'in a particular y eective manner.

Having described only a preferred form of my invention, I do not wish to limit mylpart which lits around the inner collar 25 with workin clearance.
